EXPLOSIVIF PROJECTILE.-

priming characterized by a priming holder in the head of which a flamepassage block is arranged the latter being furnished with a centralpassage charged with compressed powder or mealed powder and with one ormore slightly eccentric passages charged with mealed powder orcompressed powder. In the various constructional forms described in thespecification of the said application for patent the head of the primingholder is screwed into a socket formed in continuation of the body ofthe fuse, its bottombeing perforated with an axial passage communicatingwith the body of the fuse in such a manner that the Variable screwing ofthe priming holder into the socket causes an obtorator (which may eitherbe free or rigidly connected with one of the elements) to render thedirect passage free for the flame or to obturatethis passage to causethe flame to be transmitted through the conduit or conduits charged withcompressedv powder. The obturation ot' the communication between thefuse and the directtransmission conduit of the flame passage block isthus obtained by bringing together the priming holder and the bottom ofthe fuse body; COILVBISQLV a separation of these two elements (bottom ofthe fuse body and head of the priming holder) renders the directcommunication free.

The present invention has for its object two modifications of aparticular construction of the aforesaid invention.

According to the present inventionthe head of the priming holder isattached to a detonator body which is screwed into the projectile, thebody or the fuse having its bottom perforated with a" communicationSpecification of Letters ram.

passage and being screwed into a detachable or absence of whichindicates respectively that the projectile is adjusted for directtransmission of the Home from the primer or for retarded transmission ofthe fiame.

In order that the said invention may be more clearly understood andreadily carried into efiect I will describe the same more fully withreference to the accompanying drawings,.in which Figure 1 is alongitudinal section ofone of these constructions the parts being arranged for the directtransmission of the flame and a key for unscrewingor screwing .the ogival head being represented fitted to the latter.Fig. 2 is a partial-plan view of this key. Fig. 3 is a longitudinalsection similar to that in Fig. 1 and showing the parts in the posit-ionfor retarded operation. Figs. 4 and 5 illustrate in sectional elevationand in plan respectively a detachable collar in two pieces. Figs. 6 and7 show in longitudinal section a second constauict-ion the parts beingrepresented respectively in posi tion for direct operation and forretarded operation. ,1

The novel constructional forms comprise apriming holde'r 7 iurnishedwithits det' onating primingS and at the'center of its head 6 a flamepassage block-s ,is screwed; the latter is perforated with an axialpassage c and one or more eccentric passages b communicating with theaxial-passage. The axial passage is free or charged with mealed powderwhile the lateral passage is charged with compressed powder as shown inFigs. 1 and 3; or the lateral passage is free while the upper part ofthe axial passage 0 above the point at which the lateral passage 1)opens in charged with compressed powder as shown in Figs. 6 and 7Communication between the ruse and the ireta passage may be interruptedby fitting a projection 3 carried by the bottom a of the tusc body intothe upper part of the axial passage (3 in the example illustrated inFigs. 1 and 3; or by fitting a )rojection P. from this upper part of theaxial passage into the communication passage 2 in th' l bottom a of thel'u-' body as in theexample I illustrated in hi 1 and T.

One point of di lcrcme between the pres I ent coustructiomd forms thoseof the aforesaid application for. out is that the priming holder is notscrew .l into the body oi the fuse. The head ti oi the priming holder 78is screwed home into a detonator body 9 which is itself screwed into theegival head of the projectile. The t'use body 1 having its bottom a petated with the communication passage if is screwed into a separate ogivalhead which may itself be screwed more or less deeply into the projectilethis screwing to a greater or less depth enabling the obturator 3 to betitted into its housing for interruptingdirect ignition or the releaseof this obtiirator for cstablishing direct operation. Anothercharacteristic of the present construction is the interposition betweenthe ogival head carrying the fuse and the face of the projectile (in ahousing 13 formed in the said ogival point) of a detachable collar of adilferent metal, the presence of the collar thus indicating visibly thatthe projectile is usted for the direct transmission of the flame of thefuse to the priming holder; the absence of the collar on the other handindicating immediately that the shell is adjusted for retardedoperation. The detachable collar is made in two or more parts being shown in two parts 11 and 12 for example in Figs. d and 5; this collar ispreferably angular in cross section. The horizontal branch is intendedto be compressed between the projectile and the ogival head 10,- thevertical branch of the collar enters the projectile. An unscrewing key14; (Figs. 1 and 2) comprises two noses 1.5 which engage in notches 16in the ogival head 10. The detonator is mounted for the transmission ofthe flame (that is to say with the detachable collar ompie...ed beneaththe ogival point) for transport in the colters or bins.

in order so bring the detonator into the position for rclari'icd liringit is only necessary to llllstfl'CA' the ogival head by one or moreturns; the detachable collar is released automati ally by thisoperation; it is then only new y to allow the fragments of which thecollar is composed to fall, Whereupon the ogh at head is screwed righthome. The latter operation drives the pin 3 into its housing whether itis carried by the bottom ol the lose or by the llaine passage block.

The detonator adjusted for retarded transmission of the tlame mayreadily be adjusted for direct transmission. Inthis case the detachablecollar is replaced beneath the ogival head. The operation of modifyingthe retardation is thus reduced to two ex- 5 .z-codin lv sim leoierat-ions' l unscrewtransmission,

llame of ignition and ing the ogival. head by one or more turns and (2)screwing the said head home.

As stated above the detachable collar being formed of a difierent metalfrom that of the body of the shell and of the ogival head mereinspection of the shell will indicate for what position the retardationis adj usted.

IV hat I claim and desire to secure by Letters Patent of the UnitedStates is 7 1. In combination, a projectile body, a. removable head, twopassages provided in one of said partsone for direct transmission of theflame of ignition and the other for retarded transmission, a primingholder mounted in said body, a fuse mounted in said head, andconnections between said head and body whereby the former can be movedto obturate one of said passages.
